For some reason the navigation instruments do not go off when I switch off the switch on the dashboard.

I would understand the other way around but not this way. They are constantly under power and I have to switch them (5 x Raymarine i70s) off manually.

Plotter and autopilot drive unit on separat switches switch on and off as normal.

Does anyone have an idea or a wiring diagram for a Hanse 495?

Thanks & best regards

Edit: the switch works just fine.

Nav instruments must get their power from somewhere else.

They get their power from the nmea 2000 backbone which probably gets its power from a fuse on the main power board if they’re always on. On my 588, the MFDs and autopilot share the same switch with the backbone. If can trace the wire, it can be moved to the “Nav” switch.
